Well, like I said, the arrow glitch was patched out a few years ago. Unless you had a physical copy of the game which was unpatched, you wouldn't be able to get it to work (GotY copies would be patched, PS3 version apparently was v1.2 from the very beginning, Steam auto-installs the latest update and I don't think Oblivion appeared on Steam until after 1.2 came out?)
